Application filed April 23, 19%.

To all whom it may concern:

Be it known that I, SAMUEL HERBERT LAN- YoN, subject of the King of'England, residing at Seattle, in the county of King and State oflVashington. have invented a new and useful Car-l/Vheel, of which the#following is a specification.

This invention relates to car wheels and has for its object to provide acar wheel which will be simple in construction, and light, strongand'durable. This object is obtained by making a wheel having a webformed of one plate, said web consisting of a single plate connectingthe hub with the rim, and of an undulating or serpentine fornilengthwise, and radially between the hub and the rim, the folds of theundulations being preferably close together at the hub, and spread apartat the rim.

The invention consists in a car wheel constructed as hereinafter setfort-h and claimed.

Referring to the accompanying drawing, Figure l is a View in transversesection of' a car wheel constructed in accordance with this intention.Fig. 2 is a side View of a portion of the wheel broken away. Fig. 3 is asectional plan View, showing in developnient a portion of the web at theoutside oit the wheel hub. Fig. et is a sectional plan View showing indevelopment a portion of the web at thc inside of the rim. Fig. 5 is atransverse section taken through the rim of' a slightly modified form ofwheel, said rim being formed with a single flange.

The car wheel forming the subject of this invention is made of a singlepiece casting and includes a hub l and a rim 2. The hub and rim areconnected by a web 3 that is corrugated on lines extending radially tromthe axis of the wheel, the corrugations being of" gradually increasingwidth from the hub outward to the rim and being of gradually decreasingdepth from the hubto the'rim.

it will be seen on reference to Fig. 1 that the width of the web as awhole gradually tapers from the hub to the rim and that the corrugationsall extend on straight lines so as to better resist the strain. Thedepth of the corrugations at the rim is practically equal to the widthof said rim so that the entire surface of the latter may be supported,while the depth of the corrugations at the hub is practically equal tothe length of said hub, thus distributing the weight over the entirearea of the latter. The apexes of the corrugations extend from the hubto the rim in a straight line, and they join said parts on the saineside of 'the wheel.

ln Fig. 5 is shown a modified form of wheel, the rim 2 being providedwith a single flange l.

l claim:

A single piece cast metal wheel having hub and rim portions connected bya web, the web being corrugated on lines radiating from the axis of thewheel, the width of such corrugations gradually increasing from the huboutward, the apexes of vthe corrugations extending from the hub to therim in a straight line, and being connected to said parts on the sameside of the wheel, said oorrugations being of gradually decreasing depthandthe web as a whole gradually tapering on straignt lines from the hubto the rim, and the connections between the web the hub and the rimbeing such as to afford continuous supports for practically the fullwidth of the rim and the length of the hub.

ln testimony thatI l claim the foregoing as my own, l have heretoaliixed my signature in the presence of two witnesses.
